Welcome to the final part our 3-part series about the basic CNC terminology that new users will encounter on a day-to-day basis. Let’s wrap it up with these final 21 terms machinists will be incorperating into their daily vocabulary!
What is RS-232 used for?
What is DNC?
Direct Numeric Control.
In BobCAD-CAM software, what are Machining Features?
What does profile mean?
A standard 2D machining strategy that follows around the outside or inside of a part profile.
What is roughing?
A process for removing the most amount of material before finishing toolpath is used. Removing layers of material, stepping down in the Z-Axis while cutting.
What does plunge mean?
What is semi-finishing?
Generally used with complex 3D parts, a process in between roughing and finishing.
What is a cycle?
A complete process or sequence of processes from beginning to end.
What does bore mean?
What does counter-bore mean?
To increase the diameter at a hole’s opening.
What is a CAM tree?
What does stepover mean?
The distance the tool moves over between cuts.
What is an equidistant offset contour toolpath?
What does radial mean?
To be arranged like rays that are coming out from a common center.
What is a radial toolpath?
What does spiral mean?
To wind around a center with an increasing distance from center.
What is a spiral toolpath?
What is pocketing?
A method of cutting into the surface and hollowing out a piece of material creating a pocket.
What is thread Milling?
How does the arc fit option in 3 axis toolpaths help a customer?
It reduces lines of code and it’s easier for the machine to process 1 arc line versus thousands of small line segments.
What is cycle time calculation?
How much time it takes to machine a single part from start to finish.
There you have it! That concludes part 3 of our 3-part introduction to CAD-CAM terminology. Now that you are armed with the right lingo, the sky is the limit in your machining endeavors!
